Application inea April 19, 19.1.3. serial No'. 762,365.

To all 1li/omit may concern Be it known that I, LOUIS A. CORNELIUS, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Plumbing Waste- Pipes, of which the following is a specification.

My present invention relates to plumbing waste-pipes, and its object is to provide suoli a pipe and controlling cock which may be easily applied to wasli-basins, etc., of different dimensions and further, which shall have an improved controlling cock and further, which shall be improved in various particulars hereinafter appearing; and further, which shall be in simple, and eiiective manner combined with the overflow-pipe of the basin, etc. These objects are attained by,

and my present invention finds a preferable embodiment in, the structure hereinafter described and illustrated by the accompanying drawings, in which p n `Figure 1 is a vertical central sectional view of the whole device: Fig. 2 is a front view of the same, certain parts being shown in vertical central section on a plane at right angles to that on which Fig. l is taken: Fig. 3 is a top plan view of the same: Fig. 4 is a fragmentary View of parts on the saine sectionizing plane as Fig. 1: Fig. 5 is a horizontal section of the structure on a plane corresponding with line A-B of Fig. 1: Fig. 6 is a like view of the same, on a plane corresponding with line C-D of Fig. 1; and Fig. 7 is a side view of the cocks movable valve member.

The position of a wash-basin 1 to which my device is shown as applied, is indicated in dotted lines in Fig. 1,-the top portion at 2, and the bottom of the basin at 3. Both the waste and the overflow from the basin pass through a common outlet 5, intermedi* ate pipe 4 and ultimate discharge pipe 6. When the waste-pipe function of the device is closed by the cock 7, (in the position of the parts shown in Fig. 1,) the overliowpipe function of the device is operative, the overflow water passing from the pipe 4, through the by-pass or laterally-enlarged portion S of the vertical pipe 9, outside the cock-controlling lower pipe 10, over its top and down through it and through the hollow movable valve member 11, and is thence discharged through the ultimate pipe 6: IVhen however the cock is opened, the waste water escapes directly from the pipe'4, through the .cocks stationary valve member or valve seat 12, intov such pipe 6.

The movable valve member has a helical movement in opening and closing, being guided therein as by the iXed lug ing said members helicalgroove 14: rlhis movement is impartedthrough a spline-like engagement of the cock-controlling upper pipe 16 (carrying the rotary handle 15) with the lower pipe 10, which is concentric with and surrounded by said upper pipe, these two pipesbeing sufficiently separated as shown to permit the free passage of overliow water therebetween. The said splinelike engagement comprises the radially extending lugs 17 on the lower pipe l0 engaging the longitudinal slots 18 in the upper pipe 16.' Itl will be seen thatV such spline-like engagement permits the helical movement ofthe valve member 11, and also affords an adjustability of the device tobasins, etc., whose upper portions 2 and botto-nis 3 are at dilifenent distancesapart;M for the bearing member 19in which rotates the upper pipe 16 may be secured to the upper portion 2 as by its threaded downwardly-extending tube portion 20 with its nut 21 adapted to be screwed to its engagement with the under side of the upper portion 2 of the basin, while the lower parts-lower pipe 10, valve member 11, etc.,-are supported otherwise, as by the pipes 6, 4, etc. It will also be seen that the inner walls of the vertical pipe 9 extending, as they do, for more than an arc of 180 degrees around the valve member 11, afford it a sufficient bearing for its helical movement, although the remaining portion of this members circumference opens on the by-pass 8. It will also be seen that by reason of the lug 13 being screw-threaded as shown, it may be uiiscrewed to permit the ready disasseinbling of the parts.

Not confining myself to details of construction shown or described, I claim 1. In a device of the character described, a basin, a combined waste-pipe and overflowpipe leading from the basins outlet below its overflow level and having a valve seat, a helically movable hollow valve coperating with the valve seat and contained within and spaced from the pipe and extending above the basins outlet, a removable lug to guide the valves movement, and a rotatable handle for operating the valve in splined relation thereto.

13 engag- 2. In a device of the character described, a basin, a combined waste-pipe and over- How-pipe leading from the basins outlet below its overflow level and having a valve seat, and a hollow helically-movable valve cooperating with the valve seat and contained within and spaced apart from the pipe and extending above the basins outlet, and a handle to operate the valve.

8. In a device of the character described, a basin, a combined waste-pipe and overflow pipe leading from the basins outlet below its overflow level and having a valve seat, and a hollow helically-movable valve cooperating with the valve seat and contained within and spaced apa-rt from the pipe and extending above the basins outlet, the pipe having on one side a lateral enlargement to permit the free passage of overflow water along a portion of the valve.

4. In a device of the character described, a basin, a combined waste-pipe and overflowpipe leading from the basins outlet below its overflow level and having a valve seat, and a hollow valve coperating with the valve seat and contained within and spaced from the pipe and extending above the basins outlet, anda rotatable handle for operating the valve and having a downwardlyextending pipe with longitudinal slots and surrounding and spaced from the valve, the

valve having lugs in spline-lile engagement with the slots.

5. In a device of the character described, a basin, a combined waste-pipe and overflowpipe leading from the basins outlet below its overiiow level and having a valve seat, and a hollow helically-movable valve coperating with the valve seat and contained within and spaced apart from the pipe and eX- tending above the basins outlet, and a rotatable handle for operating the valve in splined relation thereto. v

6. In a device of the character described, a basin, a combined waste-pipe and overi'lowpipe leading from the basins outlet below its overiiow level and having a valve seat, a hollow valve cooperating with the valve seat and contained within and spaced from the pipe and extending above the basins outlet, a rotatable handle for operating the valve in splined relation thereto, and a bearing member Jfor the handle and having a threaded portion and a nut thereon for astening said member stationarily.

In testimony whereof I have hereunto set my hand in presence of subscribing witnesses.
